I was put on Cymbalta about a month ago, but for depression, not for OCD, but I also have OCD. Then, about 2 weeks ago, I went off of clomipramine (generic of Anafranil), which is a tricyclic anti-depressant which was helping with my OCD. When I went off of it, I started to get some of my OCD symptoms back, but they aren't so bad that I can't handle them, which could mean that the Cymbalta is doing good things and covering for it.
I'm interested to know how it works out for you, so keep us posted.
